ZigBee (IEEE 802.15.4) is a low data rate (20 to 250 kbps), extremely low duty-cycle (< 0.1%) system intended for periodic, intermittent, and repetitive low latency data transfer. A star topology allows peer to peer networking with up to 255 devices per network. Low power consumption and aggressive sleep modes allow a battery life of several months to several years. Although it is specified to operate in the 868 MHz, 915 MHz and 2.4 GHz ISM bands, it appears the 2.4 GHz ISM band may be the most widely used in practice.
The data rate for ZigBee is low, but spectrum spreading is used (at 2.4 GHz), which gives an occupied bandwidth of approximately 2 MHz, and allows the link to operate over a range from 1 m to greater than 100 m. Current targets are industrial and commercial applications including monitors, sensors, and automation.
